v The present machine is adapted for the purpose of loading hay or the like and com prises a frame which consists -of a pair of side members 1 converging toward their rear ends and being secured together by means of a transverse cleat 2. The forward end of the side members 1 are connected by means of a transverse beamv 3. A central supporting beam 4 extends transversely of the beams of the side members2 and constitutes a support for the main standard 5. Divergent braces 6 are connected centrally of the transverse beams 4 and have their outer ends engaging the transverse beam 3 near its respective ends. The frame is supported by means of wheels 7, `which wheels 7 are journaled upon stub axles 8, which axles 8 are held in engagement with the transverse, beam 3 by means of journals or boXings 9. Skidding shoes 10 are carried near the converging ends of the side members 1 of the frame and constitute supports for the front end of said frame. This structure is clearly illustrated in Fig. 1.

A supportingcastingll 1s carried by the main standard 5 near its upper end and this supporting standard is provided u on one side' with a depending sleeve 12 whic sleeve receives a forwardly extending brace 13. Thisbrace 13 has its lower end positioned within a casing 14, which casing 14 is carioo ried by the transversely extending beam 2. f

The casting 11 is also provided WlthI a pair of divergent socket portions 15, which ortions receive the diverging braces 16, w ich braces have their lower ends1 connected to the rear corners of the frame or the rear ends of 'the side members 1.

' of oppositely extending parallel arms 22 A crane `17 is carried by the main standard 5, and this crane carries a collar portion near' its upper end which is provided with laterally extendingsockets for, receiving a journal in adapted to constitute a bearing upon wliich the crane is to operate. The crane 17 comprises a pair of upper and a pair of lower longitudinally extendlng angle members whichl members are connected by vertically extending truss braces 18 which braces are placed at intervals throughout the entire length of the crane 17. The longitudinally extending members' of the crane 17 are also braced by means of transversely extending braces 19, andcross braces 20 for constituting a very rigid structure to withstand the weight of the lifting fork, and the hay which is adapted to be lifted thereby.

4 A journal plate 21 is carried by the inner face of the crane and upon each side of the standard 1 and this plate 21 carries a pair which arms 22 are rmly secured to the longitudinally extending parallel portions of the crane 17, the central web portion 23 being secured to the journal pin 24 which journals the crane upon the main standard 1. A lifting frame 25 is associated with the crane 17 and comprises a pair of side members 26 which converge near their up.

per ends and are secured to the journal pin 24 previously mentioned. These side members`26 carry at their upper ends spacing cleats 27 which cleats are provided with beveled faces adjacent the side members 2 6 so as to form a fiat surface t6 engage the crane and also form a flat surface to be engaged vby the nut or head of the shaft 24. vThe side members 26 of the frame are braced against spreading movement by means of cross braces 28, and to the outer ends of the side members 26 is connected the hay lifting fork 29. This fork 29 is, of course, secured to the ends of the frame 26 so as to allow the fork to swing downwardly Evhekreby the hay may be dumped from the or A A stop frame 30 is carried by the lifting fork' 29, and is braced by means of convergingbraces 31. A lifting brace `32 is carried by the hay lifting fork 29, andthis brace terminates in an eye 33, which is connected to the lifting pulley 34hereinafter described. The liftmgfork 29 is journaled upon the transversely extending shaft 35, and the stop frame 30 is braced by means of metallic braces 36, said. braces terminating in eyes 37 at their upper ends for receiving the angle stub shafts 38'of the tilting brace arms 39. These brace arms 39 are provided with outwardly extending stub shafts 38.

Cto move downwardly The upper ends of the tilting brace arms 39 are brought together and firmly clamped thereby forminga substantially V-'shaped structure as indicated in Fig. 16. A bracing cable 40 is secured to the tilting brace arms and between these tilting brace arms is placed a connecting member which may be adjusted between the brace arms for adjustably connecting the cable 40 to the brace arms 39. This cable 40 passes over a pulley 41 at the upper end of the main standard 5, and this [cable passes down through the main'standard 5, and over the pulley 42, which pulley is'journa-led upon a clamping band 43 carried by 'the main standard 5. This cable is in turn attached to a sliding head 44, which sliding head 44 works upon the auxiliary vertical shaft 45. The lower end of the shaft 45 is connected or supported by means of a bracket46, which bracket is xedly secured to the main standard 5. This bracket 46 projects laterally from the standard 5, and lis provided with a downwardlyjturned end 47, which terminates in a laterally extending end 48, as illustrated in Fig. 8. A clamp 49 is connected to the main standard 5, and also grips theI vertical shaft 45. The head 44 is held in engagement with the clamp 50 by means of a coil spring 51, and this clamp carries a pawl 52 having a gripping end 53. The gripping end 53 overhangs. the lower edge of the sliding head 44, and normally holds the head against sliding movement upon the shaft 45. A spring 54 is carried by the bracket 50, and engages the pawl 52, and this pawl 52 is connected to a vertical sliding rod 55 as indicated at 56. This rod 55 is adaptedto have vertical sliding movement andas the rod 55 is moved downwardly, it ywill be seen that the dog or pawl 52 will be drawn away from the head 44, and the head will be allowed to slide upon the shaft 45, as pressure is brought to bear upon the cable 40. This rod 55 is connected to a lever 57, which lever is pivotally secured to the bracket 46 as at 58. A roller 59 is carried by the outer end of the lever 57, and this roller is adapted to be lifted by a mechanism hereinafter described, whereby the vertical sliding rod 55 will be operated thereby causing the p awl 52 to be released from the sliding head 44.

A drum supporting casing or bracket 60 isxedly'secured to the main standard 5,

adapted to receive a crank for allowing the drum to be operated, whereby the crane 17 may be swung to its correct horizontal'position. cable 64 is wound around the drum62 and has its upper end connected to the forward end of the crane 17 by means of a hook 65. The drum supporting casing' or bracket 60 is provided with a rearwardlyextending arm 66, which arm is provided with a plurality lof adjusting apertures 67 lfor receiving the hooked end of the coil spring 68, whereby7 the coil spring may be held in an adjusted position. The drum supporting bracket 60 is provided with a transversely extending aperture 68 through which a pin 69 passes and this pin is held 1n an adjusted position by means of a plug 7 0,

which plug passes through one of the adjusting apertures 71. The outer end 72 -of the pin 69 is forked so as to straddle the coil spring as the mainsupporting shaft 5 is rotated. Through the medium of this adjusting pin 69, it will be seen that the tension'of the spring may be regulated in view of the fact that as the drum supporting cas-4 ing or bracket is rotated with the main supporting shaft 5 to such a position asto have the spring positioned within the forked end l72 of the pin 69, and a greater tension of the `spring will be produced owing to the fact that the pressure will take place from the place where the forked end 72 of the pin 69 grips the spring 68, to the end 73 of the spring 68.

The side members 1 of the` frame are provided with links or eyes 74: to which are attached chains 75, which chains are adapted to engage stakes 76 for bracing the frame while the loader is in operation. A guiding cable 77 is connected to one of the side members 1, by means'of an eye 78 and this cablel 77 is braced by means of a vertical brace 79, which brace is in 'turn braced by means of laterally extending rods 80, which rods are secured in the ground for preventing the lateral movement of the brace 79. A forwardly extending brace 81 is connected to the vertical brace 79 for preventing the brace 79 from swinging backward. A lstop 82'.is carried by the' cable 77, and is adjustably secured thereto by means of a clamp for constituting means for limitingv the distance which the horses are adapted to travel. A

chain or strap 83 may be slidably mounted.

upon the cable- 77, and may be provided with snaps for engaging the vbits of the horses for holding the horses in alinement with the guiding cable 77. The usual double which pulley may be adjustably secured ,at

different places along one of the diverging braces 6, to regulate the swing of the crane upon the main vstandard 5.

A depending link 88 is carried by the crane 17 and upon this depending link is' 7o carried a block 89, over which the lifting cable 86 passes. This cable 86 passes longitudinally of the crane 17, and passes also over a pulley carried by the block 90 supi ported upon the rear end of the crane 17. The lifting cable 86 passes over the pulley carried by the block 90, and in turn over the pulley 91 carried by the block 92. The cable` then passes over a second pulley carried by the block 90, and is in turn connected to the shaft 93 by means of a clamp. It will, therefore, be seen that as the horses travel away from the frame of theloader, the cable y will be drawn outwardly thereby lifting the hay lifting fork 29 to the position 4as shown in dotted lines in Fig. 1 and eventually llifting the hay loader so as to have the block 90, therebyv allowing the fork to tilt by means of the apparatus hereinafter described. 4

A bell crank lever 94: is pivotally secured l92 come in close proximity with the block i to the crane 17 near its'rear end, and has al forwardly extending end 95. This bell crank lever 94 is provided with a swivel collar 96, and in this swivel collar'is secured a rod 97. A nut is threaded upon each side of the swivel collar 96 for firmly connecting lthe rod 97 to the collar 96. A plurality of i guide 'links 98 are connected to the crane 1 7, and the. rod 97 passes therethrough. A chain 99 is connected tothe rear end of the rod 97, and passes over a pulley 100 carriedv by the crane, and over a second pulley 101 which pulley V`is 'carried by a vertical spring vplunger 102 carried by the collar 103, which collar coperates 'with the supporting casting 11. The end of the chain 99 is connected to the crane 7 7 by means of an eye 104. The spring plunger 102 is carried within a casing 105, and is normally held in a downwardly forced position by means ofa coil spring 106. The upper end of the support` ing casting 11 is provided with ratchet teeth for receiving the spring plunger 102, whereby the crane will be held against rotary movement upon the supporting casting 11 untilthe plunger or dog 102 is released from the ratchet teeth.

A ratchet releasing frame 107 is slidably `mounted upon the rear end of the crane 17 so as to have 'a vertical sliding movement,

andy this ratchet releasing frame ycomprises a substantially inverted U-shaped structure.'

having its side ends formed to` constitute a z substantially fan-shaped structure havinga convex lower edge 108. Each of the side portions of the ratchet releasing frame `107 is'provided witha vertically extending slot 109 in whichftravels the ends ofthe shaft 110 which supportthe pulley block y90. A laterally extending ear 111 is formed upon one'of the side members of the ratchet .releasing frame 107, and to this ear is con.- nected a lswivel head 112 in which works the arm 95.

The pulley block 92 comprises a substantially U-shaped frame 110, which frame carries a swivel connector .114 for attaching the eye 33 to the pulley block 92. The upper ends of the sides of the block 92 are flared laterally to support a circular band 115 which circular bandis adapted to engage the lower convex face 108 of the ratchet releasing frame whereby the bell crank lever 94 will `be swung so as to pull the rod 97 rearwardly thereby raising thev dog or plunger 102 out of engagement with the ratchet teeth formed upon the supporting casting 11. Of course, as .the horses continue to pull upon the lifting cable 86, the crane 17 will then be rotated to the desired point where the hay is desired to be dumped from the lifting fork 29. It will be seen that since the band 115 is made circular, the device will operate effectively no matter if the pulleys and supporting cables should become twisted. A cap 116 isv carried by the block 92, and is provided with a notched surface for taking the twist out of 'the rope as the same passes from one pulley tothe other. A projecting arm 117 is carl ried by one of the side members 1, and is braced by means of a brace 118 and to this arm 117 may be attached a stake for preventing the frame of the loader from dipping over as the ground is swung upon the opposite side of the machine.

rlhe automatic trip regulator comprises a frame 119, which frame extends vertically of the main frame of the hay loader, and is provided with an aperture through which the regulating rack bar 129 passes. The

v lower end of the frame 119 is provided with a rearwardly extending portion 121 having an upturned end 122. 4An enlarged head 123 is carried by a bolt 124,' which bolt` l fits in a notch 145 extending transversely of passes through one of the diagonally extending braces for firmly anchoring the frame 119 to the main frame of the hay loader. A plunger rod 125 is connected to the head 123, and passes through the upwardly extending end 122 of the frame 119, and around this plunger 125 is coiled a` coil spring 126 for constituting a cushion for preventing the 'severe 'jar to the automatic trip regulator after the crane has been swung to the desired position. An auxil- `iary plunger 127 is secured to the frame 119,

and passes through the depending end 128 H of the automatic trip rack bar 129. A coil spring 130`is wound upon the auxiliary plunger vrod 127, and constitutes means for `normally holding the automatic trip regulator rack ybar 129 in the position as shown ygitudinally of the diagonally extending brace 6, and allow the spring 126 to actuate. The regulator rack bar 129 is provided near its forward end with a longitudinally extending groove 131, and withinthis groove 131 is mounted an inclined lifting member. 132. This lifting member 132 is provided with a depending lug 133 which passes through an aperture formed in the rack bar 129. Several of these apertures 134 are formed' in the rack bar for holding .the inclined lifting member in an adjusted position. A channel 135 is formed longitudinally of the rack bar 1249 near one edge thereof, and within this channel is formed a plurality of ratchet teeth136. A smooth channel 137 is formed upon the upper face of the rack bar 129 so as to extend parallel with the channel 135, and the inner end of this channel 137 communicates with the channel 135 as indicatedy at 138. An ele- ,v

vating cam member 139 is secured to ther rack bar`129, by means of a Cotter-pin 140, and this cam member is provided with a downwardly inclined lip 141 for directing the outer end of the pawl 142 up out of the channel 135. The upper head of the cam member 139 is formed to constitute a cam 143- whereby when the pawl is raised up out of the channel 135, the pawl will be shifted over into the channel 137, since the cam portion 143 extends over the top of both channels so'as to direct they pawl from one channel to the other. It will be seen that as the rack bar is then drawn to its normal position the pawl will ride back through the channel 137 and assume its normal position as illustrated in Fig. 13, through the medium "of the spring 130, which will return the rack bar 129 to its normal position. A transversely extending rib` 144 is formed upon the rear of the cam member 139, and

the rack bar 129. This will facilitate the holding of the elevating cam member 139k ing tooth engaging portion 148 to swing from one channel 135 to the other channel V137. One of the arms 147 is longer than'the other, and is provided with a longitudinally extending slot for 'allowing this swinging movement. An enlarged portion 149' is formed upon the ratchet pawl 146 and through this enlarged portion passes a vertically extending rod 150, which rod carries at its upper end an adjusting thumb screw 151. The lower end of this rod 150 passes through an extension 152, and a coil spring 153 is carried by the lower end of the rod 150. This spring will allow a slight yield-V ing movement of the lower pawl 154.. The

lower pawl is of a substantially IU-shaped.

structure having a pair ofparallel arms 155, which arms extend upon each side of the frame 119. The-pawl 154 is provided with a transverse portion 156, which portion is adapted to engage `the ratchet teeth 157 formed upon the lower face of the rack bar 129. A guiding bracket 158 is formed upon 'the side of the frame 119 to limit the swing- -mg movement of the pawl 154. It will be seen that as the rack bar 129 is moved within the casing' 119 to such anextent as to cause the pawl 142 to be raised .by means of the elevating cam member 139, and the latch `or pawl 154 will4 engage the ratchet teeth 157, and cause the same to be locked against any further inward movement upon lthe frame 119. However,as soon as the pawl 142 is thrown over into the channel 137, and the pawl 154 `is kicked out of engagement with thel channel 137, the pressure of the spring 130 will cause the pawl 154 to be moved out of 157, and allow the rack bar 129 to assume its normal position.

The operation of the device is as .follows i The frame of the machine is anchored by means of the stakes described previously, and as the hay is-loaded upon the fork, the horses or draft animals are driven forward away from the frame of the hay lifter, thereby pulling upon the lifting cable 86, and causing the fork to rise so that the band 115 will engage the 107. In this manner the bell crank lever 94 will be operated raising the plunger 102 out of engagement with the ratchet teeth `formed lupon end of the supporting castthe upper U the horses continue to pull ing'll, and as upon the'cable v t volved to'the desired position. As the mam standard 5 is rotated, the roller 59 will ride upon the inclined plane or lift member 132,

thereby causing the rod `55 to be drawn downwardly and the catch or pawl 52 to be released from the sliding head-44. The head 44 will then slide downguponthe shaft 45 .and cause the cable 40 to yield thereby" allowing they journal 35. As soon as the weight is re- -leased from the fork the spring 51 will cause the head 44 to return to its normal osition `as shown in Fig. 4, and be rengage by the AYcatch or dog 52.

expanded, and will comein engagement with- For the reason that it often becomes necessary to dump the hay at different points rather than dumping the same at one point for facilitating the even distribution of the hay in its delivered condition, Ihave pro vided an automatic trip regulator, as above a pin 169 for holding the cable 64 in engagement with the drum. A locking pawl -170 'is carried by the drum supporting casing or' vbracket 60, and engages the notches '3171 formed Vupon the shaft which-supports' the drum 62. As the main supporting standard 5 is rotated, and the arm 46' is swung, thereby causing. the rack bar -129 to be slid through the frame. 119, the ratchet pawl- 142 will ride over oneof the ratchet teeth 136 formed in the rack bar 129 thereby causing g the ratchetpawl 154 to engage one of the ratchet teeth forme d upon the lowerv face of the rack bar 129 and locking the rack bar 129 in its sliding movement through the frame 1-19. It should be understood that as the arm 46 is swung the .same will engage the dependin portion 133 of the lifting member 132 t ereby causing the rackbar 129 to slide longitudinally of As .sooneas the stop occurs, ofthe .jar will be taken upby means of the spring 126,` which is wound upon the plunger 125.

Of course, it should be understood that thisinvention is susceptible yof changes in its mechanical details of construction without departing from the spirit o'f the invention.

It should be understood that the pawl 154 is adapted to prevent the rack bar 129 from beingdrawn back to its normal position by means lofthe spring 130 as the rack bar is being advanced for engagement with the pawl 142. When the sliding shoe 155 is moved longitudinally 4of the rack bar 129 so as tocause the ears 156? to be brought into engagement with ,the underv face of the rear ends 155 of the pawl 154, the pawl 154 -will be kicked outof engagement with the ratchet teeth 157 formed on the lower face of the rack bar 129, therefore, allowing the spring to pull the rack bar 129 rearwardly. The position of the sliding shoe 155 is clearly shown in Fig. 12 ready to kick the pawl 154 out of engagement with the ratchet teeth 157 formed upon the lower face of the rack bar 129.
